Diodes Incorporated AP63300 | Demoboard AP63300/1-EVM
3.8V TO 32V INPUT, 3A LOW IQ SYNCHRONOUS BUCK WITH ENCHANCED EMI REDUCTION
Overview
| Topology | Buck Converter |
| Input voltage | 3.8-32 V |
| Output 1 | 5 V / 3 A |
| IC revision | 3-2 |
Description
The AP63300/AP63301 is 3A, synchronous buck converter with a wide input voltage range of 3.8V to 32V. The device fully integrates a 75mΩ high-side power MOSFET and a 40mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.The AP63300/AP63301 device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated loop compensation network.The AP63300/AP63301 design is optimized for Electromagnetic Interference (EMI) reduction. The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high-frequency radiated EMI noise caused by MOSFET switching. AP63300 also features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time.The device is available in a TSOT26 package.
